AUTOMATIC PUMPING-MACHINE.

Specification of Letters Patent.

Patented July 5, 1910.

Application filed September 23, 1909. Serial No. 519,232.

To all whom it may concern:

Be it known that I, WILLIAM M. MYERs, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in AutomaticPumpingMachines, of which the following is a specification.

My invention relates to improvements in automatic pumping machines.

The object of my invention is to provide a pumping machine which isoperated by the weight of an animal, and is provided with means by whichthe amount of water pumped is proportionate to the weight of the animaloperating the machine.

A further object of my invention is to provide a water trough having adischarge opening and a valve controlling said opening combined withmeans actuated by the weight of an animal which comes to drink at thetrough for closing the valve, the valve being automatically opened onthe departure of the animal so as to permit the discharge of water fromthe trough that may still remain in the trough, thereby assuring freshwater for each animal.

Other novel features of my invention are hereinafter fully described andclaimed.

In the accompanying drawings illustrative of my invention, Figure 1 is aside elevation of the preferred form of my inven tion, an animal beingshown standing on the treadmill. Fig. 2 is a horizontal section on thedotted line a-Z2 of Fig. 1. Fig. 3 is a cross section, enlarged, takenon the dotted line 0cl of Fig. 1. Fig. 4: is a cross section on thedotted line e-f of Fig. 3. Fig. 5 is a vertical sectional view,enlarged, on the dotted line g-h of Fig. 2. Fig. 6 is a verticalsectional view on the dotted line 2' of Fig. 2. Fig. 7 is a verticalsectional enlarged view of the valve and parts connected therewith. Fig.8 is a side elevation ofa modified form of my invention.

- Similar reference characters denote similar parts.

In the preferred form of my invention shown in Figs. 1 to 7 inclusive aframe 1 of any suitable form is provided. Supported on the frame 1 is apump 2, preferably having a vertical reciprooative plunger 3 connectedby a rod 4. to one arm of a bell crank lever 5 which is pivoted at 1 bya horizontal bolt 6. The other arm of the lever 5 is provided with aslot 7 disposed radially to the bolt or pivot 6 and which has slidablymounted in it a block 8 provided with a lateral cylindrical projection 9on which is pivoted a box 10, which is connected by a rod 11 to a box 12rotatively mounted on a horizontal pin 13 secured eccentrically on aworm wheel 14: which in turn is secured rigidly on a horizontal shaft 15rotatively mounted. in boxes 16 supported on the frame 1. Meansoperative by the weight of an animal are provided for rotating the shaft15. When the shaft is rotated the plunger 3 of the pump will bereciprocated by means of the rod 4, lever 5, block 8, rod 11, boxes 10and 12, pin 13 and worm wheel 14.

Preferably a treadmill is provided to rotate the shaft 15. The treadmillpreferably employed comprises the following described parts: 17 denotestwo endless chain belts mounted respectively on two sprocket wheels 18secured on a horizontal shaft 19 rotative in boxes 20 securedrespectively on two blocks 21 which are supported on the frame 1. Thechain belts 17 are also respectively mounted on two sprocket wheels 22secured rigidly on a horizontal shaft 23 rotative in boxes 24: on theframe 1. Horizontal cleats or strips 25 are secured on the chain belts17 for supporting the animals which come to drink from a trough 26mounted on the frame 1 in position to receive water from the pump 2. Inthe bottom of the trough 26 is a discharge opening 27 in which issecured the upper end of a conductor 28, the lower end of whichdischarges into another trough 29 disposed below the trough 26. In theupper end of the conductor 28 is adapted to rest a valve 30, preferablymovable by gravity to the closed position and having an inverted Ushaped stem 31 which passes over the side of the trough 26 and has itsouter vertical arm slidably mounted in a box 32 secured to the frame 1.

To raise the valve the following mechanism is preferably provided :Twoangle bars 33 and 34: are respectively pivoted at their lower ends tothe blocks 21. The upper ends of the angle bars 33 and 3 1 are pivotedrespectively to the upper ends of two levers 35 and 36 which areprovided with slots 37 in which are mounted pivot pins 38 securedhorizontally to the frame 1. On the levers 35 and 36 are respectivelymounted two slidable weights 39 provided with set screws &0 for securingthe weights in the positions to w justed. The ch with rollers on theadjac their low ball 56.

The box 48 is prefer able so as to vary th will rise before it st 49..Preferably the screw threaded, the fitted in an interna supported on thefr 48 in the position i is provided with a to receive therein pin 59moun in the collar 57 A lever 60 is pivoted at one end to the frame 1and has its other bifurcated end emng the shank 52 of the friction disk50 Intermediate the ends of ereto the upper end lower end of which Whenan animal he endlessbelt be driven at a braci above the ears 53. thelever 60 is p of a vertical rod 61 the is pivoted to the box 10 walksupon the cleats of tof the treadmill, the belt will ent angle bars or 134, when the weight of an ani on the cleats 25 and chains 17, and thebar per end of the lever 3 the valve stem 31 and when the weight 0 ingon the cleats 25. the levers 35 and 36 t bars 33 and 34 when treadmill.

Secured on the shaft 23 of the treadmill is a spur gear wheel 42 whichmeshes with a pinion 43 secured on the shaft 15.

To carry ofl overflow from the lower end of the conductor 28, tendedthrough on near the upper edge thereof.

To control th by the pump 2 t anism .is preferre meshes with a w 46, thelower en box 47 on the frwhich is rotati vided at its low tion diskporti ed to bear the 50 having a c which is slida of the shaft 4 tiondisk 50 i diametrically respectivel rods 54 th the trough 26, a pipe 44is connected to its upper end being exe side of the trough 26 e amountof water supplied he following described mechd: The worm wheel 14 orm 45on a vertical shaft d of which is rotative in a ame 1, and the upper endof ve in a vertical box 48 proer end with a horizontal fricon 49 againstwhich is adaptupper side of a friction disk entral square vertical holein bly fitted a square portion 51 6. The shank 52 of the frics providedwith t opposite ears 53 t y pivoted the upper ends of two s of which arerespec- 0 swinging governor wo pairs of 0 which are e lower end tivelypivoted to tw arms 55, which are pivoted at the ends to opposite sidesof the shaft er ends are provided each with a ir upper 46 and at ablyvertically adjuste distance the disk rikes the disk portion box iscylindrical and portion being lly threaded collar 57 ame 1. To look thebox 11 which it is adjusted it vertical slot 58 adapted orizontalremovable ockin ted in a horizontal hole hich they may be adspeedproportionate tothe weight of the aniain belts 17 are provided mal oranimals walking upon it. The shaft 41 which are adapted to travel 46will thus be rotated at a speed proportionevers and ate to the weight ofthe animal on the treadmal is resting mill through the intermediacy ofthe chain depresses thereby the belts 17, sprocket wheels 22, shaft 23,gear s 33 and 34. The upwheels 42 and 43, shaft 15, worm wheel 14 5 isadapted to strike thereby raise the valve f an animal is not rest- Theweights 39 cause 0 swing upwardly the no animal is 011 the and worm 45.Rotation of the shaft 46 will effect rotation of the governor arms 55,thereby causing the balls 56 and arms to swing outwardly so as to raisethe friction disk 50, thereby swinging upward the lever 60. 1e upwardmovement of the lever 60 will move the block 8 in the slot 7 toward thepivot 6 of the bell crank lever 5,through the intermediacy of the rod 61and box 10, thereby lengthening the stroke of said bell crank lever and,of the plunger 3 of the pump 2. The length of stroke will beproportionate to the weight of the animal on the treadmill, so that theamount of water pumped will also be proportionate to the weight of theanimal doing the pumping. In case the increased work placed on the pumpby the sliding of the block 8 toward the pivot 6. does not hold thespeed of the treadmill below a predetermined rate, the disk 50 will bebrought against the disk portion 49, thereby effecting a governingaction which will prevent the speed of movement passing above apredetermined rate. By adjustingthe box 48 vertically this maximum ratemay be changed as desired.

In the operation of my invention, when one or more animals walk upon thecleats 25 of the treadmill, the mill will be set in operation, therebyoperating the pump so as to discharge water into the trough 26. At thesame time the chain belts 17 will be de flected so as to swing the anglebars 33 and 34 downward, thus, as already described, swinging the lever35 so as to permit the valve 30 to drop by gravity into the upper end ofthe conductor 28. After the animal has moved off the treadmill, theweights 39 will swing the lovers 35 and 36 in the opposite direction,and the lever 35 will lift the mitting the water remaining in the trough26 to run out through the conductor 28 into the lower trough 29. Thelower trough may be employed to water hogs.

Secured to the frame 1 at the lower end of the endless belt of thetreadmill is a horizontal timber 62, provided in its upper surface witha longitudinal groove 63 to catch the foot of the animal on thetreadmill when the foot slips olf. This timber preferably has the groove63 sharply inclined on the side adjacent to the mill, so that theanimals foot will readily slip into the groove 63 and not be caughtbetween the timber 62 and the cleats 25.

In the modified form shown in Fig. 8 for the worm wheel 14 issubstituted a bevel valve 30 to the open position, thereby per-- gearwheel 64 which meshes with a bevel gear wheel 65 secured on the shaft46. On the shaft 15 is secured a crank 66 to which is pivoted the lowerend of the rod 4:. The opening in the bottom of the trough 26 is omittedas of course is the valve mechanism which controls the said opening inthe preferred form of my invetion hereinbefore described.

The operation and construction of the treadmill are the same as in thepreferred form of my invention. When the animal passes upon the cleats25 of the treadmill, the shaft 15 is rotated by the same mechanismdescribed with reference to the preferred form of my invention. Theshaft 46 will be rotated by means of the gear wheels 64 and 65, therebyswinging upward the governor arms 55 and disk 50, so that disk 50 willbear against the disk portion 49 and control the speed of movement ofthe treadmill. At the same time the plunger 3 will be reciprocated bymeans of the rod 4: and crank 66. To prevent the trough 26 fromoverflowing it may be provided with a discharge pipe 67 the upper end ofwhich connects with the trough near the top thereof, and the lower endof which discharges into the trough 29.

I do not limit my invention to the specific constructions shown anddescribed, as various modifications of my invention, within the scope ofthe appended claims, may be made without departing from its spirit.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is

1.
